ASP.NET 6.0 - Build Hands-On Web Projects - Registering in Startup Class

The video tutorial explains how to register customer and order repositories in the startup class using the configure services method in Visual Studio. It focuses on using the Singleton service registration method, explaining its purpose and how it works across HTTP requests. The tutorial also briefly mentions other service types like add scoped and add transient, but emphasizes the use of Singleton in this context.

What is the primary purpose of registering repositories in the startup class?

• To ensure the application can access repository instances

• To configure the user interface

• To manage user sessions

• To initialize the database

What does the AddSingleton method do when registering a repository?

• Deletes the instance after each request

• Creates multiple instances for each session

• Reuses the same instance across the application

• Creates a new instance for each request

Which design pattern is implemented by using the AddSingleton method?

• Factory

• Observer

• Singleton

• Decorator

What is a key difference between AddSingleton and AddScoped methods?

• Neither creates new instances per request

• AddSingleton creates a new instance per request, AddScoped does not

• AddScoped creates a new instance per request, AddSingleton does not

• Both create new instances per request

Why might AddSingleton be preferred in the current context?

• It automatically scales with user load

• It is suitable for long-lived objects shared across requests

• It allows for multiple instances per session

• It is more efficient for short-lived applications
